. 51 WILZ/@esem g @Zambwall 13 advances, and the Water that is peller, t e water bein `driven outward, having naturally a consi erable circular motion and being artly carried around withl the impeller. or the purpose of further directing the water forward or longitudinally, and also make use of this rotary motion, a series of stationary blades are provided inside of the shell in the vicinity of these peripheral blades on the impeller. Inlthedrawing is shown a circular series of blades 23, located inside of the shell opposite the peripheral blades 21, and which are shown as carried by a ring member 24, fast in the shell. These latter blades `extend in a radial direction, and also are arranged diagonally to the transverse plane of the shell, or the plane of the impeller, but are inclined in the opposite direction from the impeller inclined blades 21. The water advanced by the propeller edge blades, will Abe received lbetween this ring member and the shell, and will engage these stationary blades 23, whose ends are arranged to engage the rear ends 22 of the propeller blades 21. The water forced longitudinally by the propeller blades, having a somewhat rotary movement,will strike these stationary blades, that will tend to somewhat change the rotary movement of the water and cause it to advance more nearly in an axial direction. In the shell beyond this rino' member and stationary blades is arranged a wall 25 extending -radially inward from the shell, but having its bore olfset from an extension 26 of the impeller hub, leavin a central space for the water advance in it into the next stage of the pump. The water after passing the stationary peripheral blades strikes this abutment wall 25 and is, therefore, driven radially inward; but this water still has a certain amount of rotary force. For the purpose of assisting in directing the water toward the central outlet of this circular part between the ring member and this wall, a series of extending blades 27 are arranged between this wall 25 at its inner portion, and the opposite face of the ring member 24. But these blades are inclined in the direction of movement of the impeller, that is, are somewhat tangential to the bore of the partition member 25. These latter blades will further direct the water inward, and it will pass out from this stage of the pump, between the bore of this wall and the hub portion 26 of the pump. It will be observed that this wall25 practically corresponds to the side wall 13 at the other end of this stage, and, as shown in Fig. 7, an-

other stage of the pump, comprising an impeller, a ring member with peripheral stationary blades and tangential blades, is arranged beyond such ring member and the adjacent wall. As shown in this figure, a series of such stages can be arranged of any number, each of which receives the Water centrally from the adjacent stage, and serves to increase its veloclty, and, therefore, its pressure, under which it is forced or advanced'. In Fig. l, and also at the outlet end in Fig. 7, 1s shown a bearing head 30 having a cap or hood 31 surrounding the outlet in the wall, to receive the water, and l which the water will be driven forward or axially or longitudinally. This longitudinally moving water having a considerably v rotary motion, is now received by the circular series of inclined blades, and these blades are 'preferably of greater number than the peripheral impeller blades; but not a multiple whereby they do not have a symmetrical arrangement. These stationary blades will receive the water advancing and also rotating and serve to direct it forward into the circular pocket beyond. And in the latter the water will be driven radially inward assisted by the. tangential bladesthat lead the water to the centraloutlet of this stage of the pump.

In the form shown in Fig. 8 the outlet arrangement is somewhat changed, the impeller 40 at the -end of the pump discharging into the stationary blades 42 on the ring 41, and from these blades the water passes longitudinally in .the end case 44 that is shown as engaging the shell 43, and provided with an outlet 45. The end case has the bearing for t-he shaft 47 on which the impeller 40 is fast. It will be seen that the partition member shown in Fig. 6 carrying the tangential blades 27 for directing the water radially inward, is simply omivted, because the water does not have to pass toward the center to engage another stage of the pump, but is led directly to the outlet of the pump at 45.
